Water cooling
The cooling system is designed as a closed, internal cooling circuit. A shaft-mounted fan
ensures circulation of the cooling air. The machine has cooling type IC71W according to IEC /
EN 60034‑6.
Cooling power
To ensure adequate cooling of the machine, it is essential to adhere to the specified cooling
water rate, temperature and cooling water quality.
Drive
The machine is designed for operation with SINAMICS converters and has been type-tested
for use with these converters. No liability is assumed in respect of damage to the motor or
converter and no warranty is issued in respect of the drive function if you operate the motor
with a different converter.
As far as the SINAMICS Motor Modules are concerned, special control software has been
developed for these motors. The converter module is selected depending on many influencing
parameters, e.g.:
● Torque
● Speed
● Overload
● Duty cycles
● Control precision
● Capable of energy recovery
More detailed information is provided in Catalog D86.2 "SIMOTICS HT‑direct". For more
